Regimen sanitatis Salernitanum, Latin: The Salernitan Rule of Health (commonly known as Flos medicinae or Lilium medicinae - The Flower of Medicine, The Lily of Medicine) is a medieval didactic poem in hexameter verse. It is allegedly a work of the Schola Medica Salernitana (from which its other name Flos medicinae scholae Salerni is derived), a medieval medical school in Salerno. This school founded in the 9th century is considered possibly the oldest medical school, in a southern Italian city, which held the most important medical information, the most famous and notable being Regimen santiatis Salernitanum. Nearly 300 copies of this poem are published, in various languages, for medical professionals. Source: Wikipedia (en)
